Be it known that l, Piume J. LAMGUREUX, a citizen of the United States, and a resident of Camas, Clarke county, State of VashinggTu ton, have invented a certainnew and useful Improvement in Drier-Rolls of Paperdi/lak` ing Machines, of which the following is a specification.

y invention relates to the Adrier rolls of paper making machinery, and particularly to the endless carriers frequently provided in such machines for conducting the leading end of the paper web between the felts of the drier rolls. 1t is required that the carriers of the leading'end of the paper web feed such end forward relatively to the speed of the periphery of said drier wise there would be a tendency for the paper web to be torn. Since the conducting of the paper web between the felts is only required when starting the web, and when the paper has been accidentally torn, and since the cai`- riers are of considerable length, their constant running imposes upon them undue wear, and causes an unnecessary expense of operation. f

Therefore the object of this invention is to provide means for supporting the endless carriers adjacent the periphery of the drier rolls, and rotatable on the aXis of the latter, but independently thereof, and means for driving' said supporting means at a speed relatively to that of the drier rolls, and to so arrange thevdriying means that they may be thrown into action as required, thus permitting the endless carriers to remain at rest when their service is not required, and in so doing saving? them from undue wear.

ih'lother result attained by this in'dention is that by means thereof the speedgof the endless carriers may bel controlled and their rotation stopped at will, which gives the operator a hotter control in the operation of feeding' the leading' rnd of the paper web between the drier rolls. Another purpose of this invention is, the means provided for accomplishing thc results mentioned are so applied to the standard foi-nis of paper makingmachines.

The means by which l attain the results mentioned are hereinafter fully described and illustrated in the ings. in which v Figure l is a diagrammatic side elevation of the drier rolls of 'the paper machine; and

The periphery f of such pulley is located adjacent 'the periphery of the drier rolls, and itis adapted for carryingthe two -endlesscarriers g. The latter run the full length of the drier roll section, on the pulleys c. and are returned to the forward end of said section over the idler pulleys 477i. llfeiglued idler pulleys, 2', maintainy said endless carriers under uniform tension.

Located above the drier roll section is pulleys 7; and q. On one end of the shaft/t' is a hxed pulley u orer which runs'thereturn portieri of one of the endless carriers/ gf.

n Claims: v

1. In a machine of the character described,

the combination with the drier rolls, oi rotatable means for supporting endless earriers adjacent` the periphery 'of the drier rolls, such means rotating on the axis of the latter but independently thereof, and means yfor independently driving said supporting to the speed of the periphlry'of said drier rolls.

2.- In a machine of the character described, the combination with the drier rolls, of rotatable means for supporting endlessv car- `riers adjacent the. periphery of tbe drier rolls, such means rotating on the' axis of the .'but independently thereof, driving journaled,

mesins, :iorsaid carriers, auch means adapted to be connected with and disconnected from the driving means of the drier rolls,

means included in said carrier, driving means for disconnecting the same from the drier rolls, and means for independently driving. said pulleys relatively to the speed of the periphery of said drier rolls.

4. In a machine of the character described, the vcombination with the drier rolls and the fixed bearings in which the same are journaled, of pulleys mounted on said ised bearings and rotating about the axis of the drier rolls, driving means, for said carriers, such means adapted to be connected With and disconnected from the driving means of the drier rolls, and means for varying the speed of the driving means ofv the carrier.
